I am creating a business (non-profit) eBay account for fundraising. I need to authorize other volunteers to create and manage listings. Must we all share a single password for logging in, or is there a way to grant permissions to other logins? It is much better from a security standpoint for each worker to have their own credentials and be granted privileges as appropriate to their role.

Update: I also created a MissionFish account through which the fees for successful sales are refunded and the sale is donated to the nonprofit. Although the organization won't earn reputation on an official eBay account, MissionFish allows designating other eBay accounts as authorized sellers. That, at least, resolves the password sharing situation.
